Field-angle dependence of sound velocity in the Weyl semimetal TaAs
F. Laliberté, F. Bélanger, N. L. Nair +5
The elastic modulus of a single crystal of the Weyl semimetal TaAs was investigated by measuring relative changes in the sound velocity under application of a magnetic fie…
Coordinate scaling in time-dependent current density functional theory
Maxime Dion, Kieron Burke
The coupling constant dependence is derived in time-dependent {\em current} density functional theory. The scaling relation can be used to check approximate functionals and in conj…
Van der Waals Density Functional for General Geometries
M. Dion, H. Rydberg, E. Schroder +2
A scheme within density functional theory is proposed that provides a practical way to generalize to unrestricted geometries the method applied with some success to layered geometr…
Van der Waals Density Functional for Layered Structures
H. Rydberg, M. Dion, N. Jacobson +5
To understand sparse systems we must account for both strong local atom bonds and weak nonlocal van der Waals forces between atoms separated by empty space. A fully nonlocal functi…
